Ligand gated ion channels

High-Yield Explanation

Ans: A. G-protein coupled receptors(Ref : KDT //e p. 399, 402 6 6h/e p. 395; Katzung 17th/e p' 377-378; lP/e p' 355)GABA-A receptors:Intrinsic Cl- channets and when open cause increase in CI- conductance and CNS depression.GABA-B receptors:G-protein coupled receptors.Baclofen is agonist and saclofen is antagonist on these receptors.
